How to Create Flashcards from Lecture Slides or YouTube Videos with Jungle

Updated

Jungle (jungleai.com) turns your own study material into practice questions: you upload lecture slides or a YouTube video, and it generates multiple-choice questions and flashcards you can review. You can start in a browser or through the iOS/Android app, and the site shows a Login / Sign Up flow, so plan on creating an account before your material is saved to a library.

What you can feed it

  • Lecture slides — the homepage's primary call to action is "Upload your slides."
  • YouTube videos — the site description lists YouTube videos alongside slides as a source.
  • Your exam style — Jungle says it can generate questions "in your exact exam style," with USMLE Step 1 and MCAT named, and more formats described as on the way.

What comes out is not just front/back cards. Jungle produces multiple-choice questions with four options (A–D), plus flashcards for spaced repetition. A sample question on the site reads: "In which part of the digestive system does most nutrient absorption occur?" with Stomach / Small intestine / Large intestine / Esophagus as choices.

Step by step

  1. Open jungleai.com and sign in. The header shows Login and Sign Up, plus a "Continue in browser" option. Use the browser if you don't want to install anything; otherwise grab the app from the App Store or Google Play.
  2. Upload your slides. Use the upload control on the landing page and select your lecture deck. Expect the source document to be the anchor for question relevance — Jungle's own benchmark scores "relevance to your document" as one of three quality dimensions.
  3. Or point it at a YouTube video. Paste the video as your source instead of a file, and Jungle generates questions from that content.
  4. Choose your exam style if you have one. If you're preparing for a specific format like USMLE Step 1 or MCAT, select it so the questions match that style rather than generic recall.
  5. Review the generated set. Read through before you drill. Jungle's published comparison shows the weak spot across platforms is plausible wrong answer choices — Jungle scored 69 there versus 55, 53, 28, and 56 for the anonymized competitors, so even the best output still needs a skim for obviously wrong distractors.
  6. Start practicing. Work through the multiple-choice questions, then use the cards for spaced repetition. One user quoted on the site, Ladedra (a vet student at SGU), describes using Jungle for "space repetition and long term studying."

Practicing beyond the cards: Monkey Tutor

Jungle includes a conversational study mode it calls Monkey Tutor. You talk through your material with it, or it quizzes you — the site's example shows the tutor pulling an image of villi and microvilli from your slide, then asking, "Your turn. Which vessel carries the absorbed fats away?" This is useful when a card feels too passive and you want to be questioned on the same source material from a different angle.

How good are the generated questions?

Jungle published a benchmark comparing itself against four anonymized competitors (later identified as Quizlet, Turbo, Gizmo, and Studyfetch) on the same three documents, scored by an LLM judge:

Dimension Jungle Competitor 1 Competitor 2 Competitor 3 Competitor 4
Relevance to your document 99 93 78 99 33
Easy to understand 94 92 85 88 89
Plausible wrong answer choices 69 55 53 28 56

Two caveats worth keeping in mind: these are the vendor's own numbers, and the judge was an LLM rather than human reviewers. The pattern that matters for your workflow is the third row — distractor quality is where every platform drops, so budget time to flag questions whose wrong answers are too easy to eliminate.

Common snags

  • You need an account. The site surfaces Login and Sign Up rather than an anonymous upload path, so don't expect to generate a set and walk away without signing in.
  • Slide quality drives question quality. Since relevance is scored against your document, a text-sparse or image-heavy deck gives the generator less to work with.
  • Don't skip the review pass. Given the distractor scores above, treat the first generated set as a draft, not a finished deck.
  • Pricing isn't stated on the pages reviewed here. Check https://jungleai.com/pricing before committing to a paid plan; nothing in the material reviewed confirms a free tier.
